  • Frequency: 1× per day
  • Route: subcutaneous
  • Half-life: ~60 hours
  • Cycle: 6 weeks on / 4 off

Research protocols frequently use a loading phase of 2–5 mg, 2× per week for 4–6 weeks, followed by a maintenance phase.

TB-500 calculator FAQ

How do I use the TB-500 calculator?+

Confirm your vial size in mg (default 5), set the diluent volume in mL (default 2), enter your target dose, and the calculator returns the concentration, the exact insulin-syringe units to draw, and how many doses your vial yields.

What's the standard TB-500 reconstitution?+

Most TB-500 research protocols reconstitute a 5 mg vial with 2 mL of bacteriostatic water, yielding 2500 mcg/mL.

What syringe should I use for TB-500?+

U-100 insulin syringes are standard for TB-500 subcutaneous administration. 0.5 mL barrels have clearer unit markings for typical research doses.

Does the TB-500 calculator support mg and IU?+

Yes. Enter your dose in mcg, mg, or IU. For IU, set the mcg-per-IU ratio (333 for HGH is a common default).
